Description

Hi,

Impalad consistently crashes on a query we tried. The explain for that query is attached in failed_query_explain.

If we alter this query to process a few days less of data, the query reliably completes and the server does not crash. See the very similar successful_query_explain attached.

This seems to be related to complex types, as we frequently run other queries on the same amount of data.

Please let me know if you would benefit from additional information (would prefer not to post query itself publicly but could email it to someone).
